A quasi-isotropic reinforced sheet material T formed by integrating a plurality of chopped semi prepreg sheet materials C including a reinforced fiber material and a thermoplastic resin material set in an unimpregnated state such that fiber directions of the reinforced fiber materials are oriented randomly in the two-dimensional direction. The average number of fibers in a thickness direction for materials C ranges is from two to ten and a thickness “t”, relative to the thickness (t.sub.p) in an impregnated state, is in a range of t.sub.p<t≤2×t.sub.p.

The invention relates to a multilayered composite film made of plastic and in the form of a surface coating for an article, wherein the composite film is at least partly transparent, i.e. is transparent in partial regions, has at least one outer transparent top layer which is optionally provided with a transparent coating, and has, on the rear side of the top layer, one or more further transparent plastic layers and also a transparent carrier layer, wherein arranged inside the layer composite is an opaque layer which is in the form of a sheet-like masking or diaphragm provided with openings and is transparent only in the openings of the masking or diaphragm, wherein the opaque layer adjoins the rear side of the top layer in the direction of the carrier layer, wherein the base material of the opaque layer is the same as that of the top layer.

In various embodiments, an improved flexible-composite material is described that comprises at least one scrim constructed from at least two unidirectional tape layers bonded together and at least one woven fabric, non-woven fabric, or membrane bonded to the scrim. In various embodiments, the unidirectional tape layers comprise a plurality of parallel fiber bundles comprising monofilaments within an adhesive resin. In various embodiments, the fiber bundles are separated by gaps that can be filled in by adhesive or non-adhesive resin.

Composite materials include a steel matrix with reinforcing carbon fiber integrated into the matrix. The composite materials have substantially lower density than steel, and are expected to have appreciable strength. Methods for forming composite steel composites includes combining a reinforcing carbon fiber component, such as a woven polymer, with steel nanoparticles and sintering the steel nanoparticles in order to form a steel matrix with reinforcing carbon fiber integrated therein.

Composite materials include a steel matrix with reinforcing carbon fiber formed of individual fibers penetrating into the matrix to substantial depth. The fibers typically have defined diameters and large ratios of penetration depth to fiber diameter. Specified methods for forming the composite materials have a unique ability to achieve the large ratios of penetration depth to fiber diameter.

Composite materials include a steel matrix with reinforcing carbon fiber integrated into the matrix, and having unreinforced regions suitable for stamping or other deformation. The composite materials have substantially lower density than steel, and are expected to have appreciable strength within regions having the reinforcing carbon fiber, while having greater deformability in unreinforced regions. Methods for forming composite steel composites includes combining at least two laterally spaced apart reinforcing carbon fiber components, such as a carbon fiber weave, with steel nanoparticles and sintering the steel nanoparticles in order to form a steel matrix with reinforcing carbon fiber integrated therein, and unreinforced regions located in the lateral spaces between carbon fiber components.

A floor panel includes at least two reinforcing layers extending in a direction parallel to a plane defined by the panel to allow one of the at least two reinforcing layers to be situated at a level between 30˜70 percent of a thickness from a top surface of the panel to a highest part of a top surface of the tongue, and/or a bottom surface of the panel to a lowest part of an upper surface of the lower lip.

A composite comprising a non-fibrous organic polymer aerogel layer having a first surface and an opposing second surface and a support layer having a first surface and an opposing second surface is disclosed. An interface can be formed between a portion of the first surface of the aerogel layer and a portion of the second surface of the support layer such that the aerogel and support layers are attached to one another. A majority of the volume of the aerogel layer does not have to include the support layer. The composite can have a thickness of 3 mils to 16 mils.
